18082b1b3f Sema: Don't set "validation started" bit on typealiases in the ITC 
This appears to do nothing except cause a crash.

55ffbe8cce AST: Fix Type::transform() for protocol compositions 
There was undefined behavior here; we were calling
members.append(members.begin(), members.begin() + index),
which is invalid because 'members' is the new array of
members being built, which is empty at this point!

Add test case for crash triggered in `swift::TypeChecker::checkDeclAttributesEarly(...)`.

Current number of unresolved compiler crashers: 37 (5544 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `loc.isValid() && "Diagnosing attribute with invalid location"` added on 2017-04-22 by you in commit 25ce6fa2 :-)

Assertion failure in [`lib/Sema/TypeCheckAttr.cpp (line 39)`](df10b0fe02/lib/Sema/TypeCheckAttr.cpp (L39)):

```
Assertion `loc.isValid() && "Diagnosing attribute with invalid location"' failed.

When executing: void (anonymous namespace)::diagnoseAndRemoveAttr(swift::TypeChecker &, swift::Decl *, swift::DeclAttribute *, ArgTypes &&...) [ArgTypes = <swift::Diag<> &>]
```

Assertion context:

```c++
  void diagnoseAndRemoveAttr(TypeChecker &TC, Decl *D, DeclAttribute *attr,
                             ArgTypes &&...Args) {
    assert(!D->hasClangNode() && "Clang imported propagated a bogus attribute");
    if (!D->hasClangNode()) {
      SourceLoc loc = attr->getLocation();
      assert(loc.isValid() && "Diagnosing attribute with invalid location");
      if (loc.isInvalid()) {
        loc = D->getLoc();
      }
      if (loc.isValid()) {
        TC.diagnose(loc, std::forward<ArgTypes>(Args)...)

3806292ae2 [swiftc (34 vs. 5544)] Add crasher in swift::TypeChecker::resolveWitness 
Add test case for crash triggered in `swift::TypeChecker::resolveWitness`.

Current number of unresolved compiler crashers: 34 (5544 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `Conformance->getTypeWitness(assocType, nullptr) ->isEqual(type) && "Conflicting type witness deductions"` added on 2017-04-04 by you in commit 5c89eb84 :-)

Assertion failure in [`lib/Sema/TypeCheckProtocol.cpp (line 2497)`](a5b5609137/lib/Sema/TypeCheckProtocol.cpp (L2497)):

```

Assertion context:

```c++

c3fcfd2c26 [swiftc (32 vs. 5544)] Add crasher in swift::Expr::walk(...) 
Add test case for crash triggered in `swift::Expr::walk(...)`.

Current number of unresolved compiler crashers: 32 (5544 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `ty->getNominalOrBoundGenericNominal() || ty->is<DynamicSelfType>() || ty->isExistentialType() || ty->is<ArchetypeType>()` added on 2014-02-25 by you in commit 6a532e05c :-)

Assertion failure in [`lib/Sema/CSApply.cpp (line 7121)`](5c1859e98a/lib/Sema/CSApply.cpp (L7121)):

```
Assertion `ty->getNominalOrBoundGenericNominal() || ty->is<DynamicSelfType>() || ty->isExistentialType() || ty->is<ArchetypeType>()' failed.

When executing: swift::Expr *(anonymous namespace)::ExprRewriter::finishApply(swift::ApplyExpr *, swift::Type, swift::constraints::ConstraintLocatorBuilder)
```

Assertion context:

```c++
  }

  // We're constructing a value of nominal type. Look for the constructor or
  // enum element to use.
  assert(ty->getNominalOrBoundGenericNominal() || ty->is<DynamicSelfType>() ||
         ty->isExistentialType() || ty->is<ArchetypeType>());
  auto ctorLocator = cs.getConstraintLocator(
                 locator.withPathElement(ConstraintLocator::ApplyFunction)
                        .withPathElement(ConstraintLocator::ConstructorMember));
  auto selected = getOverloadChoiceIfAvailable(ctorLocator);

7ef9041111 [swiftc (30 vs. 5544)] Add crasher in swift::GenericSignature::getConformanceAccessPath 
Add test case for crash triggered in `swift::GenericSignature::getConformanceAccessPath`.

Current number of unresolved compiler crashers: 30 (5544 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `inProtocol->isRequirementSignatureComputed() && "missing signature"` added on 2017-03-08 by you in commit 1f8b0f9b :-)

Assertion failure in [`lib/AST/GenericSignature.cpp (line 857)`](aae1b681e7/lib/AST/GenericSignature.cpp (L857)):

```
Assertion `inProtocol->isRequirementSignatureComputed() && "missing signature"' failed.

When executing: auto swift::GenericSignature::getConformanceAccessPath(swift::Type, swift::ProtocolDecl *, swift::ModuleDecl &)::(anonymous class)::operator()(swift::GenericSignature *, const RequirementSource *, swift::ProtocolDecl *, swift::Type) const
```

Assertion context:

```c++

      // Canonicalize this step with respect to the requirement signature.
      if (!inProtocol->isRequirementSignatureComputed()) {
        inProtocol->computeRequirementSignature();
        assert(inProtocol->isRequirementSignatureComputed() &&
               "missing signature");
      }

      // Get a generic signature builder for the requirement signature. This has
      // the requirement we need.
      auto reqSig = inProtocol->getRequirementSignature();
```

63bc717963 Error when one associated type is constrained to another. (#10053) 
(...is constrained to be a subtype of another)

Previously the compiler would just mark the entry in the inheritance
clause invalid and move on without emitting any errors; in certain
circumstances in no-asserts builds this could actually lead to
everything working "correctly" if all conforming types happened to
pick the same concrete type for both associated types. In Swift 4 this
can actually be enforced with a same-type requirement, which will
guarantee that the two associated types are the same even in generic
contexts.

This fix avoids assertions and crashes, but the diagnostic is still
incorrect, and in the simple case of the inheritance clause it's
redundant. Doing something better and possibly even downgrading it to
a warning in Swift 3 mode is tracked by rdar://problem/32409449.

Initial patch by Slava, fixed up by me.

5998cd645f [ConstraintSolver] Penalize conversions from String to UnsafePointer 
There are possible situations when we find solutions with String
and String -> UnsafePointer conversions at the same time for
expressions with default string literals. In order to disambiguite
such situations let's prefer solutions without String -> UnsafePointer
conversions if possible.

solution.

f09d2ad397 [ConstraintSolver] Forbid forming solutions with free generic type parameters 
`FreeTypeVariableBinding::GenericParameters` mode allowed to bind
all free type variables with fresh generic parameter types, which
is incorrect (at least) if there are multiple generic solutions
present, because such parameters couldn't be compared.

This mode was used for code completion, which is now switched to use
`FreeTypeVariableBinding::UnresolvedType` instead.

49ddd96c83 Added documentation and test coverage. 
compare_perf_test.py is now covered with unit tests and public methods are documented in the implementation.

Minor refactoring  to better conform to Python conventions:
* classes declared in new style
* proper private method prefix of single underscore
* replacing map with list comprehension where it was clearer

Unit test are executed as part of validation-test.

.gitignore was modified to ignore .coverage and htmlcov artifacts generated by the coverage.py package

a9733cb8db [GSB] Resolve dependent member types in same-type and superclass constraints. 
Once we're finalizing same-type-to-concrete and superclass
constraints, replace any unresolved DependentMemberTypes with their
resolved counterpairs. This allows us to simplify
DependentGenericTypeResolver, which only builds unresolved
DependentMemberTypes now, and eliminates the penultimate use of
ArchetypeResolutionKind::AlwaysPartial.
